I have tested different tools (MlRawViewer 1.1.3, MLVMystic 0.3, MLV Converter 1.9.1, MLVViewSharp) for converting MLV to DNG-files. The generated DNGs are compared in two Photoshop layers (I have set Difference blending mode). The results are different (I use default settings in tools).
Only two cases are equal - MLV Converter (Chroma Smooting = none) is equal to MLVViewSharp tool.

Questions:
1) Why DNG results are different? Do convertors change the native RAW-data stored in MLV file? What algorithm or base code they are use?
I noticed MLV Converter has mlv2dng.exe. Is it base code core for MLV processing?
2) How to get native RAW (DNG) from MLV? What tool export the true result without any modifications?
3) What tool get the best result? As I understand native RAW-data from camera maybe with some artifacts.
4) Now I use MLV module. Is any different between .MLV and .RAW video modules? Are .MLV and .RAW frames equals?





Thanks!
